- Recommending both the conjugate and polysaccharide pneumococcal vaccines to all U.S. seniors may have little public health impact and be economically unreasonable. Public health impact and cost-effectiveness of using both vaccines in all adults aged ≥65 years were estimated compared with an alternative strategy (omitting pneumococcal conjugate vaccine in the nonimmunocompromised) and with the newly revised recommendation (giving or omitting conjugate vaccine based on patient–physician shared decision making).
- Tradeoffs exist between efforts to increase influenza vaccine uptake, including early season vaccination, and potential decreased vaccine effectiveness if protection wanes during influenza season. U.S. older adults increasingly receive vaccination before October. Influenza illness peaks vary from December to April.
- The 13-valent pneumococcal conjugate vaccine (PCV13) is approved by the U.S. Food and Drug Administration for adults, but its role in older adults is unclear.
